摘要: The invention relates to an actuator (1) for a valve, in particular turbine comprising valve spindle (3), adjustment of opening position (D) the and drive piece (5) (3). is connected by means storage device (7), which may be pre-tensioned value (Fv) during pre-tensioning process, such manner that, with (7) can set without altering (Fv). Said particularly suitable on steam or gas turbine. In preferred embodiment comprises hydraulic damping unit (61), integrated piston (27). permits reliable end-travel case rapid closure.
